Inventor: KIMURA TAIJI
IPC: A23B4/00
Filed: 1984-09-21
Abstract: PURPOSE:To prepare pellets liberating O2 stably for a long time when it is thrown into water without causing crumbling in the water by molding a mixture consisting of a specified ratio of calcium peroxide, gypsum or siliceous sand, calcium orthophosphate, MnO2, and carbon. CONSTITUTION:After mixing 10-50pts.wt. calcium peroxide, 10-50pts.wt. gypsum or siliceous sand, 20-45pts.wt. calcium orthophosphate, 3-8pts.wt.

Abstract: PURPOSE:To reduce the number of components by forming a focus of a diffracted light from a prescribed area of a diffraction element to this side of a photodetector and a remote side at the focusing state of an optical system so as to detect focus/tracking error. CONSTITUTION:A luminous flux radiating from a semiconductor laser 12, reflected in an optical disk 16 and diffracted at areas 13a, 13c of a diffraction element 13 is converged to a focus f1 to form light spots P1, P3 to photodetection sections 17a, 17c of a photodetector 17. On the other hand, the luminous flux diffracted at areas 13b, 13d is converged to a focus f2 to form light spots P2, P4 on photodetectors 17b, 17d. Then the size of the spots P1-P4 is equal at the focus state but reduced/magnified at the defocus state. Thus, a focus error is detected from a difference between sums of output signals of photodetector element on diagonal lines and a tracking error is detected from the phase difference between the difference of the sums and the sum of the output signals of all the photodetector elements by using one photodetector. Thus, the number of components of the photodetector.

Title: Channel selection means for television receiver
Inventor: KASAHARA YASUHIRO
IPC: H04N5/44
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To improve the operability of the channel selection means by having only to select and designate a specific channel among plural sub images so as to display a sub image onto a screen. SOLUTION: A memory circuit 19 has a capacity of a multiple of N of a pattern number and stores channel information of a sub image while classifying the information based on classification of broadcast signals. When the operator uses an operation means 15 to designate an optional classification by a sub image display section 31, a 2nd channel selection control means 14 displays a sub image corresponding to the designated classification onto a television screen from a display processing means 18 based on the information from the memory means 19. When a more interesting displayed sub image is in existence than a man image, the operator uses a sub image selection section 32 to designate the image, a 1st channel selection control means 13 switches a reception channel of the main image into a reception channel of the designated sub channel automatically.  Thus, in the television receiver where the plural sub images are displayed on the television screen together with the main image, the channel of the selected sub image is displayed on the TV screen by having only to designate a specific channel in the plural selected sub images by a sub image selection section 32.

IPC: A61B5/00
Filed: 1991-07-12
Abstract: PURPOSE:To provide a method of arranging recording papers automatically for each person as being fed continuously from an electrocardiogram in a group examination. CONSTITUTION:A mount 5 is fed continuously onto the rear of a recording paper 2 being fed from an electrocardiograph to be cut with a cutting blade after both are sewn with a sewing machine 10. They are first, folded in two with a first folding blade 15 and a folding roller 16, subsequently folded in four with a second folding blade 18 and a folding roller 19 and finally, the personal recording paper 27 folded in four is dropped into a stocker 23.
